Harmonicity VoiceNet dimension guide
Spectral & Timbralcode vn_HARMslot 63
This dimension measures the ratio of periodic signal to aperiodic noise. Below: the merge-scaling dose-response for the __high and __low LoRA (laion/moss-voicenet-dimension-loras) at 25/50/75/100/125%, the measured target value at each dose, the top-3 ± correlated EmoNet emotions and VoiceNet dimensions, three audio samples per dose, and a grounded prompting tip. Costs are shifts vs. the 24-sample neutral baseline in genuineness, vocal-burst blend and speech quality.
Harmonicity controls the ratio of periodic signal to aperiodic noise. The __high LoRA shifts it +0.33 at 125% (worst cost: burst-blend -0.40); the __low LoRA shifts it -0.09 at 125% (worst cost: burst-blend -0.21). The __high direction is the stronger, more reliable knob here.

Merging Harmonicity __high drives the dimension: at the recommended 125% dose the measured Harmonicity score moves from a 0.25 baseline to 0.58 (a +0.33 shift). The dose-response is clean and monotonic — each step pushes the dimension further. That reach is a steep cost — the biggest hit is to burst-blend (-0.40); across the board genuineness -0.12, burst-blend -0.40, speech quality +0.02. Emotionally it reads as Teasing (r 0.49), Triumph (0.44) and Contempt (0.43), and it moves away from Affection, Longing and Relief. On other voice dimensions it co-moves most with Articulation Clarity (0.85), Arousal Shift (0.85) and Attack (0.84), while pulling down Vulnerability, Disfluency and Genuineness. Practical call: merge __high at 100–125%; expect Teasing and Articulation Clarity to rise and burst-blend to fall. If you don’t want Teasing bleeding in, offset it with a prompt cue toward Affection to keep the harmonicity shift without the side-effect.

Merging Harmonicity __low pulls down the dimension: at the recommended 125% dose the measured Harmonicity score moves from a 0.25 baseline to 0.15 (a -0.09 shift). The dose-response is mostly ordered but noisy between doses. That reach is a real cost — the biggest hit is to burst-blend (-0.21); across the board genuineness +0.00, burst-blend -0.21, speech quality -0.05. Emotionally it reads as Contemplation (r 0.36), Interest (0.35) and Affection (0.26), and it moves away from Distress, Pain and Fatigue/Exhaustion. On other voice dimensions it co-moves most with Valence Shift (0.73), Recording Quality (0.70) and Articulation Clarity (0.69), while pulling down Disfluency, Casual Style and Respiration. Practical call: merge __low at 100–125%; expect Contemplation and Valence Shift to rise and burst-blend to fall. If you don’t want Contemplation bleeding in, offset it with a prompt cue toward Distress to keep the harmonicity shift without the side-effect.
